Apparatus for making welts

Abstract

Abstract A double or single welt for use in the upholstered furniture and other industries, as well as a method and an apparatus for making such welts. The double welt comprises an elongated strip of textile or other material with its longitudinal edges folded or rolled inwardly to ward each other to form two tubes, into which cords are preferably introduced, the outer surface of teach infolded edge portion engaging the inner surface of the unfolded central portion of the strip and being permanently secured thereto as by adhesive, the cords being free to move longitudinally within the strip material. The single welt may be formed by slitting a double welt made as stated, or by forming a single fold or tube from a narrower strip of material, utilizing essentially the same method of folding or rolling the material upon itself, inserting a cord if desired, and securing the outer surface of the folded material to the inner surface of the unfolded material. An apparatus suitable for performing the stated method comprises a folder mechanism, an adhesive applying means, and means for advancing the material (and cords if used) through said mechanism and past said adhesive applying means.
